SPT-CL J0205-5829: A z = 1.32 Evolved Massive Galaxy Cluster in the South Pole Telescope Sunyaev-Zel'dovich Effect Survey
B. Stalder, J. Ruel, R. Suhada +80
The galaxy cluster SPT-CL J0205-5829 currently has the highest spectroscopically-confirmed redshift, z=1.322, in the South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) survey. XMM-Ne…
Galaxy clusters discovered via the Sunyaev-Zel'dovich effect in the first 720 square degrees of the South Pole Telescope survey
C. L. Reichardt, B. Stalder, L. E. Bleem +77
We present a catalog of 224 galaxy cluster candidates, selected through their Sunyaev-Zel'dovich (SZ) effect signature in the first 720 deg2 of the South Pole Telescope (SPT) surve…
Chandra observations of NGC4342, an optically faint, X-ray gas-rich early-type galaxy
Akos Bogdan, William R. Forman, Ralph P. Kraft +10
Chandra X-ray observations of NGC4342, a low stellar mass (M_K=-22.79 mag) early-type galaxy, show luminous, diffuse X-ray emission originating from hot gas with temperature of kT~…
Exploring the unusually high black hole-to-bulge mass ratios in NGC4342 and NGC4291: the asynchronous growth of bulges and black holes
Akos Bogdan, William R. Forman, Irina Zhuravleva +10
We study two nearby, early-type galaxies, NGC4342 and NGC4291, that host unusually massive black holes relative to their low stellar mass. The observed black hole-to-bulge mass rat…
Cosmological parameters constraints from galaxy cluster mass function measurements in combination with other cosmological data
R. A. Burenin, A. A. Vikhlinin
We present the cosmological parameters constraints obtained from the combination of galaxy cluster mass function measurements (Vikhlinin et al., 2009a,b) with new cosmological data…
The Ysz--Yx Scaling Relation as Determined from Planck and Chandra
Eduardo Rozo, Alexey Vikhlinin, Surhud More
SZ clusters surveys like Planck, the South Pole Telescope, and the Atacama Cosmology Telescope, will soon be publishing several hundred SZ-selected systems. The key ingredient requ…
